(When I came back, I saw that the recommendation tickets for a few days were not very good. Brothers, the excessive chapters have been completed. What's wrong? Brothers, the villagers' chrysanthemums are now dead, and they are terrible... Brothers who are fine can go and check it out on the new author's new book signing list...)

During the New Year’s Eve dinner, Yun Fei didn’t eat a bite of food, and he was poured wine from the time he served on the table.

In the end, he didn't know how to get off the table, how many times he vomited, and didn't remember. He was confused and was helped to his single dormitory. He slept in bed for two days before he got out of bed with weakness.

In the past two days, Luo Xiaoli was running around and serving tea and water every day. Yun Fei was afraid of delaying this secretary who was no bigger than him, so he resolutely refused the female secretary's attentiveness. However, Luo Xiaoli didn't care about Yun Fei's attitude at all, and still did his own way to make food and feed water.

As the Chinese New Year is getting closer, there are many people going home to celebrate the Chinese New Year in the factory, but the entire factory did not stop production because of the Chinese New Year. The original two shifts became a normal working and rest time because many people asked for leave.

Although Yun Fei said he wanted to leave, he has not resigned now and still occupies the position of deputy director of Qingfeng Machinery. Around the Chinese New Year, although there were a lot of orders in the entire factory, Yun Fei did not force the workers who stayed in the factory and did not go home to work overtime. After being busy for so much half a year, everyone took advantage of the Chinese New Year to relax for a few days.

The improvement of the factory organizational structure made him, the deputy factory director, idle. Even without him, there would be no chaos in the production of the entire factory in a short period of time. Yun Fei, who was waiting for Ren Zhiguo's news, was also lazy to wander around the workshop, staying in his office every day, thinking about adding standard PMC axis drive modules to the three-axis machining center.

This is quite simple in theory. But in actual operation, it is extremely complex. It not only involves electronic circuits, hydraulic and pneumatic, and the linkage of several different axes. The most important thing is to design a microcontroller that can control at least four axes to link at the same time.

The so-called microcontroller is to integrate a computer system into a small silicon wafer. In later generations, this thing was used in a lot of places, such as mobile phones, telephones, calculators, home phones, etc., most electronic products will be used.

A microcontroller can also be said to be a simple computer. However, the microcontroller used by CNC machine tools is not comparable to those used in these small electrical products. In this era, CNC machine tools used were all dedicated industrial control chips. Since the technology is far less developed than later generations, most CNC machine tools use dozens or even hundreds of industrial control chips in series at the same time to meet the control of various complex actions by the machine tool during processing.

In China, research on microcontrollers has just begun. Yun Fei doesn't know where to find someone who can develop industrial control chips that can control a four-axis machining center that performs a large number of complex operations at all times. He only knows about microcontrollers.

In his previous life, Yun Fei had thought of studying microcontrollers when he was studying for graduate school, but later he found that almost all those who swept the streets were graduate students. In that era when it was better to study for a few more years than to stay in a few more years, Yun Fei entered the factory after graduation.

The difficult job is to find, which made him a bachelor who followed the workers to learn machine tool operation technology. From the simplest start, it took him ten years to get to the level of a senior technician. For Yun Fei, who was not doing his job properly, but also learning machine tool operation with the workers, not only did the leaders have any opinions on him, but his colleagues in the entire department criticized him.

Yun Fei didn't care about his colleagues' ridicule. At least, the income and status of ordinary technicians like him were far from comparable to those of the masters of skilled workers.

In the factory where Yunfei used to be, many masters in their thirties and forties work as the most ordinary operators, but receive higher salaries than department managers. Every time they have new product development, department managers have to say good things to those experienced and skilled masters.

If someone makes the master unhappy, he will just throw his work: "If you have the ability, you will stop doing it..." Even the company boss has to say good things to coax.

Why is this? Isn’t it because of the superb skills in his hands? The master will never worry about not being able to find a job. Many small factories support these masters, or even provide for them. This is not for anything else, but just to be able to use his skills and experience to make the product when encountering high-precision and difficult mechanical parts.

As we all know, the higher the accuracy and the greater the processing cost of parts, the higher the processing cost, which means the greater the profit. Yun Fei once encountered such a thing many times in a friend's machining factory.

Once, a friend had to use a complex special-shaped part on the equipment of the factory, which required processing holes on eight surfaces, and each hole could not exceed 0.02mm error. After finding countless outsourced processing factories, others dared not take over the drawings when they saw them, and even refused without asking about the price. In the end, the friend had no choice but to find an old technician in the aerospace system through relationships. Others just looked at the drawings for a while, and then quoted a processing fee of 20,000 yuan!

Someone said that you should use a machining center with a diameter of more than five axes. The person who said this is definitely someone who doesn’t know much about machining centers. Because no matter what kind of high-end equipment you need to clamp parts during processing, any high-end machine tool cannot be extremely shaped and needs to be clamped for such a mechanical part product that needs to be processed at one time.

As long as the processing cannot be completed in one clamping, the accuracy requirements for position degree cannot be guaranteed.

Yun Fei was present at the time and felt chill in his heart. This was simply a rude blackmail! He thought that no matter what, the processing fee for a part with a big fist could not be so outrageous! However, his friend agreed happily on the spot and asked the master if the 20,000 yuan was enough.

Yun Fei was stunned at that time.

In the end, when I saw the master working, his mouth was so open that he could stuff an egg. The master spent three days doing a few small work clothes, and the processing time was only less than an hour for eight sides. In this less than an hour, the time to actually start the machine tool will definitely not exceed five minutes! The rest of the time is used to correct it!

Finally, Yun Fei asked the master, why did he get such a high price after doing it in such a short time? Isn’t this obvious blackmail?

The master told Yun Fei: "This is the price of technology and experience."

Finally, Yun Fei's friend told him that the master said that the master was right, this is the price of technology and experience. If the part does not have the space dimensional accuracy limitations between the eight sides, any advanced technician can do it. The four-axis or five-axis machining center can only process the six sides of the part at the same time, and the position of the two sides and these processed surfaces will be difficult to control.

After all, even the most precise CNC machining center will have processing errors. The processing errors will accumulate. The machine tool is not a human, and it is not known to automatically eliminate the processing errors generated.

Later, Yunfei met a repairman who repaired the equipment they bought after spending tens of millions of dollars in the company. Dozens of repair engineers in the entire factory worked for several days but couldn't find the reason. In the end, they could only find repair personnel through agents.

That repair cost 10,000 yuan. What the repairman did was just reconnecting a very small wire!

Yun Fei's boss was angry at that time: "You said that you can only connect such a wire, which is worth ten thousand yuan? If our engineers come and do it, they won't even cost ten yuan!"

The maintenance master smiled on the spot: "Indeed, it costs less than 10,000 yuan to connect this wire. My charging structure is like this - the wiring fee is one yuan. If you find the wire to connect it, it will cost 9,999 yuan."

This is technology; this also requires incomparable experience!

Because of these, Yun Fei firmly believed that if you want to become an excellent mechanical technician, you must be familiar with the operation of various equipment and master the performance of various machine tools. Only by understanding these can you be a good technician better. Otherwise, you don’t even know how to process, or even what equipment you need to use to process the products in your hands. After the task is arranged, the operator just said: "I’m sorry, I really can’t do this. The master has never taught me back then, so why don’t you teach me how to get an octahedral on the lathe without loading the car..."

Yunfei once met a top colleague. The guy had just come out of school and studied mechanical design, but he was responsible for the process in Yunfei's factory. He directly found a miller and asked the miller to mill out threads on an ordinary milling machine.

The Chinese New Year was about to come, not only did Ren Zhiguo not show up, but he didn't even call him.

Yun Fei was becoming more and more anxious. He could count on the military behind Kamat to provide him with a group of various talents to develop PMC axis drive modules hung on the three-axis machining center. Without the various experienced technicians and engineers in the hands of the military, he alone, unless he has the superpowers in the online literature or carries a super computer from alien civilizations, how can he create a fourth axis involving countless professionals?

Tomorrow is February 2, 1992, the 29th day of the twelfth lunar month, and the Chinese New Year will be held on February 3rd. Until now, there is still no news from Ren Zhiguo. Yun Fei is a little nervous and began to think about how he should start without the support of the military behind Kamat.

Working in Qingfeng Machinery is not only because Yunfei does not have the original funds to start, but more importantly, this talent is in an era of state monopoly. It is so difficult to open a technology-intensive and capital-intensive factory.

The sky gradually darkened. Yun Fei was smoking a cigarette in the office and pondering what he should do after the New Year. He could not have stayed at Qingfeng Machinery and waited for an unknown result.

The originally planned trip to the vast number must be ahead of schedule. We cannot wait until August to create a low-end system that cannot be lower-end. If that happens, the things we planned will be even more distant.

He didn't want to see that the high-end machine tools in the entire country were printed in German or English twenty years after he came to this world.
